John Deere stops running

I have a 2003 JD GX 345. It will start with the choke on. Then it will run for about 15 seconds and then stop (either with the choke on or off). So far I have changed the modular, fuel filter, fuel lines. I have also checked the fuel pump, which is working just fine. Also, I have cleaned out the carburator. Any ideas on what else it could be?

make sure you have fresh gas.Also, check the vent line on the carb and make sure there"s no spiders in there. You said you replaced the time delay module? How about the fuel shutoff solenoid, is it clicking when you cycle the key?

I have been down a similar rd with my Onan powered Bowlens... After going through the ignition several times, I found that it was the Carburetor FLOAT that was sticking intermittently ....!! Re'worked the float Needle and it only seldom sticks now.. Hard to locate the correct (Small Seat and Needle) For this Onan 2 cylinder..

Have you replaced the key switch? They develop a "bad place". (some of that high quality that justifies the high prices)Try wiggling the key back and forth towards the start position and see if it keeps running.

As an old Farmall guy my first response is that's normal for a JD, or it probably ran out of fuel it's a JD. To be serious does it have an engine protection systen that shuts the darn thing off if there is no/ low oil pressure or it's to hot? might be someting worth looking at I ask this because you say it quits with the choke in or out indicating the choke is not doing a lot, some of the protection gizmos have a little bit of delay in them, or is it quiting when you let off the key?

Easy on the anti Deere comments. Every thing that is mechanical can and will have problems at some point. As for IH there will never be another one on this farm. It's something about waiting for hydraulics, slow steering, holding the clutch down and hoping the non sycro transmission goes in gear without taking a tooth off that I don't miss. Oh and one other thing, what about that famous TA. I've never seen a deere with a quad shift to low and roll over a hill at high speeds without holding back. And keep in mind this is the John Deere forum page. I have enough respect for other peoples opinions that I wouldn't say these things on your page.
